This data set is part of a larger data harmonization effort to make lake sediment core data machine readable and comparable. Here we standardized grain size data of sediment core PG1982, retrieved in 2009 from Lake 09-Tik-09 (Yakutia, Russia) at 4.7 m water depth. The thermokarst lake 09-Tik-09 is situated in the forest tundra and has one outflow an one inflow. It lies at an elevation of ca. 116 m a.s.l. with a surface area of ca. 0.383 km2 and a maximum lake water depth of estimated 6.3 m. The 1.28 m sediment core was retrieved by a UWITEC hammer action gravity corer during the RU-Land_2009_Lena-transect expedition of the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research (AWI, Germany, Potsdam) in cooperation with the North Eastern Federal State University (NEFU, Russia, Yakutsk). Grain-size was measured using a Coulter LS 200 Laser Diffraction Particle Analyser at AWI Potsdam.
